Wi-Fi 6E is the new name given to Wi-Fi 6 – Extended in the 6 GHz band. It was named by the Wi-Fi Alliance in order to distinguish IEEE 802.11ax devices capable of operating in the 6 GHz unlicensed band.
Regulators around the world are looking to open up the 6 GHz band for unlicensed use. The FCC in the United States approved the use of unlicensed Wi-Fi signals in the 6 GHz band in April and it looks likely that European Countries will follow suit in early 2021.
What are the advantages of Wi-Fi 6E?
More channels means no congestion
The 6 GHz band adds up to 59 new 20-MHz channels. This will ease congestion straight away as Wi-Fi 6E devices will be able to operate in channels with no co-channel Interference (CCI) or adjacent channel interference (ACI) even in dense environments like stadiums or airports.
Wider channels enable faster speeds
With 14 new 80-MHz and 7 new 160-MHz channels, the 6 GHz band provides enough contiguous spectrum to allow deployments of wide channels, enabling the fastest Wi-Fi throughput.
No legacy devices means reduced latency
The 6 GHz band is reserved for 802.11ax devices meaning only fast and OFDMA capable devices are allowed, decreasing network latency.
Wi-Fi 6E testing challenges
As with Wi-Fi 6, Wi-Fi 6E also brings up some new testing complexities and challenges. We’ll discuss these in greater detail in a forthcoming blog, as well as going through how to solve them.

802.11ax (Wi-Fi 6 & 6E)
As the next-generation of Wi-Fi, 802.11ax (Wi-Fi 6) is designed for our everything-and-everyone connected world. Previous generations of Wi-Fi have been about speed, 802.11ax is about efficiency and speed and providing that speed to multiple users at the same time.
Throughout these posts, you’ll learn about the key RF-PHY changes made in Wi-Fi 6/802.11ax compared to Wi-Fi 5 and older generations: the addition of a new frequency band, higher modulation rates, smaller subcarrier spacing, longer guard intervals and the introduction of the OFDMA modulation technique providing capacity improvements and latency reduction.
